3 Claims. (Cl. 110-18) This invention relates to incinerators for burning trash and other refuse.

An object of the invention is to provide an incinerator construction capable of improved combustion by reason of a unique dome and air inlet arrangement.

Another object of the invention is to provide a lined upper hot gas chamber of round design and whereby the lining therein expands and contracts evenly, thereby reducing cracking of the liner.

A further object is to provide an incinerator wherein the charge door may be rotatably positioned relative to the stack projecting from the side of the incinerator body and whereby the incinerator may be installed for convenient use in the corners of basements or the like.

A further object is to provide an incinerator which may be fired and left unattended with comparatively complete safety.

These and other objects of the invention will become apparent from the following description and the accompanying drawing, wherein:

Figure 1 is a vertical section and broken elevation of an incinerator embodying the features of the invention.

Figure 2 is an elevation of the incinerator shown in Figure 1, but with the dome rotated 90 with respect thereto.

Figure 3 is a top plan view with the dome removed and with the stack shown in transverse section.

In the drawing, the numeral 10 generally designates a cylindrical body of steel or other suitable material. The lower end of the body 10 is open, as at 11, and is provided with a flange l2 therearound for resting on a fireproof surface, not shown. Spaced from the bottom 11 and integral with the inner wall of the body 10, there are inwardly formed brackets 13 supporting a removable perforated grate 14. The inner surface of the body 10 above the brackets 13 is lined with a cast fireproof liner 15 having extremely low thermal conductivity. A breech 16 is provided in one side and near the upper end of the body 10 and communicates with and supports a smokestack 17 having a spark arrester 18 on its upper end. A cap 19 is provided on the spark arrester to keep out rain. The breech 16 is also lined, as at 20, and upwardly and inwardly directed tubular ports 21 are provided therearound for admitting additional air to the stack 17 and, as will become apparent, aids combustion.

Within the wall of the body 10 opposite the breech 16 there is a perforated door 22 mounted on hinges 23, and which door is located immediately above the grate 14. Similarly, there is another perforated door 24 in the body 10 below the grate 14 and positioned beneath the last described door 22 for removing ashes.

A primary feature of the invention is the removable dome shaped top 25 which is formed of an outer shell 26 ited States Patent F 2,859,716 Patented Nov. 11, 1958 and provided with a fireproof liner 27. The liner 27 is cast and is held in place by means of an inwardly directed flange 28 which rests on an inwardly directed flange 29 around the upper end of the body 10. A depending rib 30 overhanging the upper periphery of the body 10 prevents lateral movement of the dome 25. An eye 31 projects upwardly from the upper center of the dome 25 for convenience in raising and turning the latter. A charge opening 32 is provided in the dome 25 near the base thereof, and which opening is formed through the shell 26 and the liner 27. Ears 33 project from the outer surface of the dome shell 26 and are arranged one above the other and on one side of the opening 32. A hinge rod 34 rotatably mounted in the cars 33 support a perforated door 35 which is rigidly secured to said rod by means of brackets 36. The lower extending end of the hinged rod 34 is angularly formed and disposed beneath the door 35 and is spaced therefrom for convenience in charging the incinerator.

By reason of the rotatable mounting of the dome 25 on the body 10, the charge door 35 may be positioned at any desired rotated angle with reference to the stack 17. Moreover, the shape of the dome 25 uniformly heats the liner 27 therein, thus reducing the possibility of cracks due to expansion and contraction. Additionally, the dome provides a hot air chamber for aiding combustion, and by reason of the location of the charge door 35 with respect to the breech 16, together with the additional air inlets through the stoking door 22 and ash removal door 24, an eflicient combustion takes place.

The invention is not limited to the exemplary construction herein shown and described, but may be made in many ways within the scope of the appended claims.

What is claimed is:

1. An incinerator comprising a hollow body including a circular open upper end, a horizontal grate within said body and spaced from the bottom thereof, a perforated door within said body above said grate, a cast ceramic liner within said body above said grate, a dome above said body, an inwardly directed flange around the periphery of said dome and in rotatable sliding contact with said body around said circular upper end thereof, a charge door in said dome, a cast ceramic liner in said dome, the lower edge of said liner being supported by said flange, an outwardly extending breech in said body at the upper end thereof, and a smokestack On the extending end of said breech.

2. An incinerator as defined in claim 1 and wherein the charge door therein is perforated, and wherein there is a perforated door in said body below said grate.

3. An incinerator as defined in claim 1, and including tubular ports in the extending portion of said breech.
